Application filed January 23, 1909. Serial No. 473,926.

To all whom it may concern: 1!

Be it known that I, CEoIL HOLMES THOMP- SON, a subject of the King of Great Britain, residing in the city of Toronto, in the county of York, in the Province of Ontario, Dominion of Canada, have invented a new and useful Improvement in Ventilating Tater- Closets, being an improvement on my United States Patent No. 858,427, dated July 2, 1907, of which the following is a specification.

My invention relates to the arrangement of a cut-01f valve forming part of the hinge by which the seat and cover is fastened to the bowl of the closet. The valve part of the device is situated between an inlet, andv outlet passage formed in the hinge part, and to the inlet passage is coupled a feed pipe, and to the outlet passage is coupled a spray pipe. The feed pipe is for the purpose of conveying a supply of water to the valve and the valveis arranged to be operated or opened when weight is placed upon the seat which will allow the water to pass through the valve into the spray pipe and through the spray pipe and out through the nozzle coupled to the outer end and projecting into a vent pipe coupled to the bowl of the closet. lVhen weight is placed upon the seat the valve opens and the water passes through the valve and into the vent pipe and by the spray from the nozzle a suction is created by whichthe odors are drawn from the closet and forced out through the vent pipe. The spraying action continues as long as weight is placed upon the seat, but the moment the weight is removed the valve closes and discontinues the spraying action.

the supply of water to the valve is entirely separate from the flushing arrangement of the closet, but if I so desire the parts may be arranged in combination to operate tospraying discontinues the water in the vent pipe flows back into the bowl and aids in the flushing of the closet. I attain these objects by the device as illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of a section of the closet showing the parts in position; Fig. 2 is a side elevation of the device with details of the bowl, seat and cover; Fig. 3 is a top plan View of Fig. 2; Fig. 4: is a sectional view on lines a--a Fig. 3; Fig. 5 is a cross sectional view on lines 6-?) Fig. i

3; Fig. '6 is a'detail sectional view of the spray nozzle and'ventpipe;

Like characters refer to like parts throughout the drawings and the specification.

a is the bowl of the-closet, b the hinged seat, and 0 the hinged cover.

Extending rearwardly from the top plane of the bowl is an extension cl on which is bolted the valve mechanism. 6 designates the valve casing which also constitutes a part of the hinge, and at each end of the valve easing e is a fastening post f, formed with a screw threaded stem f adapted to pass through an opening formed in the extension (Z of the bowl, and on the end of each of the stems f is a fastening nut g, by which the fastening posts are firmly held in position on the bowl. Pivotally connected to the valve casing c are hinged parts it by which the cover is hinged to the bowl, and 2' designates other hinged parts by which the seat section is hinged to the-bowl.

j represents the water supply pipe, and coupled between the inlet end of the valve casing and the feed water supply ;pipe is a coupling pipe 70.

l designates a vent pipe coupleduover the top or to side of the bowl and adapted to be carried and extended through the roof or chimney of the buildings in which the closet is set up. Extending into the ventpipe is a spray nozzle m, the spray 'nozzlem may be of any suitable form but for all practical purposes the form asshown in the drawings consisting of an ordinary tube with the end closed with a small flaring opening a, formed through the top, is the most practical for the purpose. Coupled between the outlet end of the valve casing and the spray nozzle is a coupling pipe 0, by which the water is carried from the valve casing to the spray nozzle m, to be discharged into the vent pipe.

The valve consists of the casing 6 having formed in it an inlet port land an outlet port 2.

3 is a plug, screw threaded, and adapted to be screwed into the valve casing for the purpose of maintaining the piston 4 of the valve in position. The piston is formed with a spindle 5, adapted "to extend through the bottom of the plug 3, and pivoted to the projecting end of the spindle 5 is a lever arm "6. Surrounding the spindle within the plug 3 and adapted to engage between the web of the plug, and a washer surrounding the spindle adjacent to the piston head is a helical compressible spring 7 adapted to maintain the piston head against the seat of the inlet port to keep the valve closed and also to return the piston to its normal position after the valve has been opened for the purpose of spraying.

The lever arm 6, extends forwardly from the valve, and is adapted to engage under the closet seat 6, and by reference to Fig. 2 in the drawings it will be noticed that tile lever arm supports the back end of the seat slightly raised from the bowl, in which position it remains until such time as weight is placed upon the seat, the back end of the seat lowers as sufficient latitude is provided by the connection between the hinged parts 2' and h, and the valve casing as each of the hinged sections are formed with elongated slots at the point of coupling with the valve casing to provide for the adjustment of the seat with the back end of the bowl. By the lowering of the back end of the seat which is supported raised on the lever arm, the lever arm will be forced downward with it, by which action the lever arm draws downward a piston head 4, away from the seat of the inlet port 1, and allows the water to pass through the pocket 8.

10 designates a rubber washer fitted on the spindle 5 of the piston which engages against a shoulder 11 formed by the forma tion of the piston head and spindle. The washer is interposed between the web of the plug 3 and the shoulder of the pocket 8 formed in the valve casing, and is for the purpose of preventing the water from escaping down through the opening 12 through which the spindle 5 passes in the plug 3.

As illustrated and described. the valve arrangement in my invention is of the lift valve nature, but I may so arrange the combination that a slide valve may be adapted for the purpose, the main object of my invention lying in the arrangement of a valve to open and close the flow of water to a spray nozzle in the vent pipe.

When the spray is being made in the vent pipe it will strike against the inner surface, and as it condenses, a certain amount will trickle back through the spray by its own weight, and when the pressure is entirely out off, the condensation in the vent pipe will drain itself back into the bowl, and will aid in flushing.
